4" ST 5-14 - submersible pump
The 4" ST 5-14 submersible pump by IBO is a multi-stage centrifugal device with a diameter of 100 mm, powered by three-phase 400 V current. Thanks to increased resistance to sand and floating rotors, it also works reliably in intakes with poorer water quality. It is used to supply water to houses, farms and to power irrigation systems.
For whom
- Owners of single- and multi-family houses - constant, reliable water supply from their own deep well.
- Agricultural farms – increased resistance to sand and continuous operation are suitable for intensive water consumption.
- Irrigation system users - the pump powers sprinklers and drip lines as well as drainage installations.
- Installers – Power supply three-phase and durable construction facilitate selection for more demanding installations.
Application
The 4" ST 5-14 deep well pump is designed for pumping clean water from drilled deep wells and for increasing the pressure in water supply systems. It is used to supply water to single- and multi-family houses, farms, in heat pump installations and to power irrigation and drainage systems.
The pump operates in a vertical position, immersed in a well with a minimum internal diameter of 115 mm. The pumped water must not contain mechanical impurities beyond the permissible sand content, and its temperature should not exceed 35°C. The 4" ST 5-14 400V submersible pump is a durable solution for long-term operation on the farm.
Features of the 4" ST 5-14 pump
The 4" ST 5-14 pump is a multi-stage centrifugal device with a diameter of 100 mm, powered by three-phase 400 V current. The use of floating impellers and increased sand resistance allow for reliable operation in intakes where standard submersible pumps would experience accelerated wear. The permissible sand content is up to 5%, and the engine is oil-cooled.
Thermal protection built into the motor winding protects the device against overheating. The suction and discharge bodies are made of brass, the housing, shaft and rotor are made of AISI 304 stainless steel, and the impellers and diffusers are made of PPO polymer. The mechanical stuffing box works in a SiC/SiC/NBR system. The pump is standardly equipped with a 2 m power cable.

Frequently asked questions (FAQ) – submersible pump 4" ST 5-14
What is the 4" ST 5-14 submersible pump used for?
The 4" ST 5-14 pump by IBO is used to pump clean water from drilled deep wells and to increase the pressure in water supply installations. It is suitable for supplying homes, farms and irrigation systems.
How does 4" ST differ from 4" STM?
4" ST pumps are powered by three-phase 400 V, while 4" STM are powered by single-phase 230 V. The hydraulics of both versions are the same, and the choice depends on the type of power supply available in the installation.
In which well can a 4" ST 5-14 pump be installed?
The pump can be installed in a well with a minimum internal diameter of 115 mm, in a vertical position. The maximum immersion depth is 150 m, and the discharge port should be at least 2 m above the lowest water level.
Can the 4" ST 5-14 pump handle water with sand?
The pump has increased sand resistance thanks to floating impellers and allows for a sand content of up to 5%. However, remember that pumping sandy water shortens the life of the working elements.
What liquids cannot be pumped with the 4" ST 5-14 pump?
The pump must not be used for salt water containing corrosive, flammable, petroleum-based substances or long-fiber pollutants. It is also not suitable for food or water with excessive mineral content.
Where can you buy a 4" ST 5-14 submersible pump?
As a manufacturer, we do not sell directly. The 4" ST 5-14 deep well pump by IBO can be purchased from our trading partners, installation wholesalers and authorized online distributors.
What warranty is covered by the 4" ST 5-14 pump?
The 4" ST 5-14 submersible pump by IBO is covered by a 24-month (2-year) manufacturer's warranty. Warranty service and post-warranty service provided by Dambat.
